As Fig. 1, Fig. 2, Fig. 3 and shown in Figure 4, the device for folding of collapsible vehicle, comprise the little joint 2 of the body that is fixed on the front vehicle frame 1, be fixed in the body big joint 7 of back on the vehicle frame 3, amount to switching mechanism and amount to safety mechanism, rivet rotationally in back vehicle frame 3 and the little joint 2 of body.

Described amount to switching mechanism comprise amount to switch 5, snap close 6, the iron plate 12 that resets, registration mast 13 and retracing spring 14.The described switch 5 of amounting to is connected by the big joint 7 of rivet 4 and body, amounts to switch 5 and can drive snap close 6 rotations; Described snap close 6 its lower ends prop up the clamp of amounting on switch 5 inwalls 17, and its upper end cooperates with fixed leg 15 on the front vehicle frame 1, and when snap close 6 hooked fixed leg 15, the front and back vehicle frame connected, and during snap close 6 releases, the front and back vehicle frame separates, and is collapsible; Snap close 6 is rotatably connected on the big joint 7 of body, also is provided with a boss 18 on the snap close 6; Registration mast 13 is fixed on the vehicle frame 3 of back, and retracing spring 14 is inserted in registration mast 13, and a side of the iron plate 12 that resets is connected with retracing spring 14 bottoms, and the boss 18 on opposite side and the snap close 6 offsets.

The described safety mechanism of amounting to comprises safety button 10, retracing spring 11, insurance card post 8.Safety button 10 is arranged on body big joint 7 lateral surfaces (as shown in Figure 1), and as shown in Figure 3, safety button 10 is comparatively smooth v-shaped structure, and its top is passed by rivet 9, and it is rotatably mounted in the button hole 16 in the big joint 7 of body.Inboard one end of safety button 10 is provided with an insurance card post 8, and this insurance card post 8 passes the housing in the big joint 7 of body, limits to amount to switch 5.Press safety button 10, then insurance card post 8 outwards moves, and discharges doubling and runs the spacing of pass 5 jointly.The other end of safety button 10 inboards is connected with retracing spring 11; The other end of retracing spring 11 is tight against button hole 16 inwalls, make safety button 10 under normal conditions when (during non-pressing) insurance card post 8 limit and amount to switch 5, promptly must press safety button 10 earlier, just can open and amount to switch 5.

As shown in Figure 2, amounting to switch 5 is rotatably connected on the big joint 7 of body by rivet 4 with snap close 6; Amount to switch 5 and be the housing structure shape, snap close 6 is S-shaped, and the upper end is a hook-type, but clasp firmly is fixed in the fixed leg 15 on the front vehicle frame 1, and the lower end props up amounts to switch 5 inwalls, and the inwall of amounting to switch 5 is provided with clamp 17; The expansion force of retracing spring 14 makes snap close 6 remain closely buckling state, avoids causing vehicle frame folding because of accidental causes such as vibrations break off relations snap close 6.

When needs are folding, because the vehicle frame of collapsible vehicle the right and left all is provided with device for folding, two hands are pressed safety button 10 simultaneously with forefinger or thumb about needing, then insurance card post 8 outwards moves, no longer block and amount to switch 5, make and amount to switch 5 and can mention, mention with the little finger of toe and the third finger this moment and amount to switch 5, along with amounting to mentioning of switch 5, the snap close 6 that drive is amounted in the switching mechanism rotates, the fixed leg 15 that snap close 6 is broken away from the front vehicle frame 1, thus make front vehicle frame 1 and back vehicle frame 3 break away from mutual buckling state, realize that car load is folding.Its deployed condition and folded position are respectively as Fig. 2, shown in Figure 4.

When needs launch, depress safety button 10, insurance card post 8 outwards moves, switch 5 is amounted in release, the upper end clasp of snap close 6 is lived the fixed leg 15 of front vehicle frame 1, when front vehicle frame 1 and back vehicle frame 3 mutually behind the fastenings, the expansion force of retracing spring 14 makes snap close 6 remain closely buckling state, avoids causing vehicle frame folding because of accidental causes such as vibrations; Amounting to insurance card post 8 that safety button 10 in the safety mechanism makes by the effect of retracing spring 11 to be fixed on the safety button 10 simultaneously moves inward to block and amounts to switch 5, make and amount to switch 5 and cannot be raised, promptly, safety button 10 is under retracing spring 11 effect, and insurance card post 8 makes to be amounted to switch 5 and keep locking-in state always; Promptly play the effect of safe double insurance.
